What it is and where it fits
The ABB 1SBN010134R1011 is a CAL4-11K auxiliary contact block, belonging to the Contactors and Starters category under the Auxiliary Contacts subcategory. It mounts onto ABB contactors to provide additional signal or control-circuit switching, typically in a motor control center or panel enclosure where you need to mirror the main contactor's state or interlock with a PLC input.
